I realize this suggestion comes a bit late, since bennos managed to get rid of the offending files, but another option might have been to download Delete Doctor, which is capable of erasing files, and folders, that Windows XP thinks are uneraseable.

here's the best fix, for anyone else who gets stuck on this one. I discovered it after trying several other things.

symlcsvc.exe is the Sym LC Service. It's part of Norton Internet Security. It should be removed by either uninstall or Norton Removal Tool, but that didn't happen on my machine. You can verify that it's running by looking in Task Manager. The clue is the last 3 letters of the file name -- svc.

If you stop this service, you can delete its file, along with the two dll's. You also should disable the service, so it won't try to start again when you re-boot.
